The MST Aluminum Adjustable Body Post is an upgrade for the FXX-D, RMX 2.0 and MS-01 D models, and is easily installed by sliding it over your existing body posts. The machined aluminum option will help to add strength to the body posts and provide a rigid structure for the body, while the available color options will give your ride a custom look that cannot be matched by the stock parts. Package includes two body posts, body clips and hardware.
